BUILDER MECHANISM FOR YARN-WINDING MACHINES.

implication filed May 1, 1925. Serial No. 27,177.

To all whom it may concern:

Belt known that 1, Homes ll, Bunon'r'r, a citizen of the United States, and a resi I dent of Hopedale, in the county of VVorcester and State of l'vlassaohusetts, have invent- This invention relates to builder mechanisms tor yarn winding or spinning niachines.

In that type of looms known as feeler loonos it is now the common practice to wind filling carriers" or bobbins for use in such; looms by providing a few preliminary windings upon/the filling carriers or bobbins, technically now known-as a bunch, and upon the completion of such preliminary windings or bunch. to pass to the regular service windings, and various types of lnechanisniis have been devised for this pur-. pose. One of the ob ects of the present invention is to provide a builder mechanism with a bunch building attachment of simple and novel character which is readily'appli- 'cable to builder mechanisms now in co1ninon use and which has for ts purpose to preliminary windings or bunch and then to automatically pass to the regular service windings when the bunch has been eo1n-" pleted. lVhen such wound filling carriers or bobbins are employed in'-l'eeler looms" the preliminary windings or bunch lnsure that a complete shot of filling shall be laid in the shed on the last pick of the shuttle prior to filling replenishment.

lVhen the builder mechanism: passes l'roin the bunch to regular service windings, it is desirable that the builder arm and perforce the connected yarn guides, such as a ring rail, for instance, will not juinp,and another-nnportant teature of the present 1n'- ventlon consists in means associated with the bunch building elements for preventing such pimp.- v

In winding successive yarn carriers or hobbins'itis iinportant'that the massof yarn constituting the preliminary windings or bunch shall be uniform or of the same amount, and another feature .of the invenbecause rier or bobbin that the bunch-on the successive bobbins or successive series of bobbins shall contain the I same amount of yarn. This is, important the yarn in the bunch usually con stitutes waste when filling replenishment is etlected in the loom, and, a predetermined knowledge of the amount of such waste gives data for determining the amount of yarn which shall constitute the bunch in a successive series. I

The invention, novel features thereof, and new combination of parts willbest be made clear from the following description and the accompanying drawings of one good form of the invention, which in its true scope will be definitely set forth in the claims;

In the drawings: Fig. or winding machine having vention associated therewith;

Fig. 2 is a frontelevation, with some of the parts shown in section, and illustrating more particularly the relation'of the ele ments during the bunch building operation; Fig. 3 is an enlarged side elevation ofthe parts shown in Fig. 2;

Fig. 4 is a similar side elevation to that the present inwshown in Fig. 3, but illustrating the relation o t parts after the COIIlPlQtlOIl of the bunch and during main winding" and Fig. 5 is a side elevation of a filling carhaving the bunch wound thereon.

The advantages of the present invention are well manifested inconnection with a spinning machine, and as shown in the present embodiment thereof, the spinning machine is of the ring type, but, obviously, the invention is not'restricted thereto as it may be advantageously employedin connection with any machine for winding bobbins avith filling wind.

1 is a perspective view of a spinning In the drawings, the machine frame 1 for supporting the operating parts maybe of" any usual or well-known type, and, as shown,'cons1s ts of end frames of usual character connected by a cross-member 2 and a, fixed spindle rail 3 on which the filling carriers-or bobbins to be supplied with yarn are rotatably mounted; Above the spindle rail 3 is the ring rail 4 of usual construction and having the spinning rings othroughwhich the filling earriersor bob- .bins 6 extend." Secured to the'ring rail tion, therefore, consists of means to insure down movement efiect the traverse of the ring rail to lay the yarn upon the yarn rewives or bobbins, As shown, the lifter rods 7, of which there may be any suitable number, have shoes 8 which rest upon the pin or roller 9 upon arms 10 mounted for rocking movement in supporting brackets 11 secured to the machine frame. The arms 10 are secured, in the present instance, to the transverse shaft 12'to which is connected (an arm 13 having a weight 14 normally tending tolift the ring rail'or yarn guide. Secured to the rock shaft 12 is the arm 15, usually known as the segment arm, which is connected to the builder mechanism, to be hereinafter described, by means of a flexible connection or chain 16, and in order that the various lifter arms 10 may be moved in unison, the rock shafts 12, of which there may be .any suitable number, are connected together by a rod 17. The above described mechanism is of the usual type and the 'detailsthereof form no essential part of the present invention.

Pivotallymounted on the machine frame at 18 isthe builder arm 19, the rearwardly extending tail end of such arm, as at 20, being provided with a counterweight 21 for normally holding the follower 22 against the peripheral portion of the main builder cam 23, which is. driven from an suitable source of ower, as usual in this general type of bui der mechanisms. As shown, the main builder cam is mounted upon a shaft or stud 24 supported by the machine frame.

The builder arm 19 carries the usual letback drum to which one end of the flexible eonnectlon or chain 16 -'is'-secured, as at 26, and said drum 25 carries a worm gear 27 which is giyen a rotative movement to let back on the flexible connection 16 through a worm28 mounted on the worm shaft 29' and provided with a pick wheel 30, the construction being such'that as the :builderarm-is raised and lowered, the pick wheel 30 is 'stepped along by the usual pick mechanism '31 to let back on the flexible connection 16. ,These featuresmay be as usual in builder mechanisms nowin common use.

In accordance with the resent invention, lhebmlder arm is provi ed with a wo'rm whichis normally under the influence of means for moving the worm transversely relative to the builder arm into bunch build ingrelation with a rotating bunch building device, t,he construction being such that the worm is restrained from;movement-to bunch building position during regular windings,

by the rotating bunch building device but is permitted to move'to bunch building po sit on relative thereto when the builder arm .is de ressed;

M specifically, the builder arm, in the present instance, is provided with a bracket or support 32 which may be appropriately uman secured to the builder armfby pins or bolts 33. In the present instance, the bracket or support .32 is provided with slots 34 through which the pins or bolts 33 extend, and ad justing screws 35 serve to effect proper ad justment of the bracket with respect to the builder arm.

The downwardly extending portion 36'of the bracket, Fig. 2, ca'rriesa worm which is normally; pressed laterally of the builder arm to impart to the worm a tendency to assume ,its bunch building position.' In the present instance, the pin 37 is secured to the lower extending portion 36 of the bracket and is provided with screw threads 38, whereby the pin 37 may be adjusted laterally of the builder arm by means of an adjusting. nut 39 or other suitable adjusting means... The pin 37 has the enlarged or shoulder portion 40 on which is mounted a worm 41, the hub portion .42 of which embraces the enlarged portion 40 of the pinand has a limiting shoulder 43. Between the inner face of the worm and the bracket arm 36 is interposed a spring 44 normall tending to move the worm 41 laterally o the bui der arm into bunch building position relative to the rotary bunch builder device.

The rotary bunch builder device may be mounted for rotating movement through any suitable connections, but as shown in the present instance of the invention, the rotary bunch builder'device, 45 is constituted as a disk and is secured by bolts 46 to the main builder cam 23, suitable shoulders 47 being interposed between the rotary bunch builder device 45 and the outer face of the bunch builder cam. The rotary bunch builder device has a peripheral edge portion 4&adapted to travel in the grooves of the worm 41, with the result that when the er device, the bunch will have been com-v pleted.

From the construction thus far described, it will be apparenp that thebuild'er arm has 'mounted thereon a bunch building member or warm 41 which is normally. under the influence of the spring 44 tending'to move it laterally from the builder arm ,into bunch building position for cooperation with the retating bunch building device 45, and "when the builder arm 19 is depressed. the spring 44 acts at once to project or move the worm 41 into bunch building position, as indicated in Fig, 2. h

Dur ng main service windings, it 'is necdolled, it"is usual to depress the ring rail for dofiing, the winding machine at such :times being at rest or sto ped. When a fresh unwound sauce of filing carriers or bobbins have been su plied to the machine g and the latter is rea y for commencing to .wind it new series of filling carriers or bobbins, the machine attendant will depress the builder arm, thereby carrying downwardly I 1 the worm 41 from the position shown in Fig.

4 where the outer face of the worm bears against, the side of the rotary bunch builder device, andthe spring 44 will at once move the worm outwardly into bunch building-relation with therotary bunch builder device ,45, so that on lettin up the bunch builder arm the'machine Wi be set to commence the preliminary or bunch windings. As theretary bunch builder device rotates during the bunch building operation, as indicated inFig. 2, the worm 41 will be rotated to move it backwardly against the normal acof the spring 44, until when the end of wvorm is presented to the rotary bunch I builder device 45, the builder arm will rise com ' from the action of the counterwei ht 41 and rail to cause the outer face 0 the worm to r against the side of the rotary bunch build 1' device 45, and the follower 42 will {a into fen agement with the regular "builder cam, w ereupon the windings-pf the filling carriers or bobbin's will be continued with regular service wind.

.The amount of yarn to be contained in the preliminary windings or bunch will be determined by the extent of movement of 45 lathe worm 41 outwardly into bunch biiilding position when the builder arm 19 is depressed, and the amount of such movement may be conveniently regulated or deter-' mined by adjustment of the nut 39 on the threaded-portion 38 of the pin 37 which carrice the worm 41.

', In'passing from bunch building to reg- 'ular servicelwind, it is desirable-that the builder arm and perforce the connected yarn guides or ring rail shall not jum and to effect a gradual approach of the ollower 22 into contact with the periphery of the main buildercam as the worm 41 1S moved outwardly .andfinally leaves the edge of the rotary bunch builder device 45, the outer a I face portion of the worm 41 is provided with a scroll track .49 of gradually decreasing I -radius, as indicated in Figs. 1, 3 and 4,.wlt

' the result that as the worm is moved out-' wardly from its bunch building position,

tween the rotary bunch builder device will permit the builder arm to gradually rise until the follower- 22 takes upon the peripheral portion of the main builder cam. Thus, all

objectionable shocker jump in passing from the bunch builder wind to the main builder wind is avoided. i

Since the Worm 41 is "rotatable under the action of the rotary bunch builder device 45, it follows that when the outer face 50 of the worm boars upon the side of the ro- 'tary bunch builder device during regular service Wind, that the worm 4]. is liable to turn under the frictional engagement with the rotary bunch builder device. The effect of this would be to causctlie \voriuto pre sent variablccircumferential portions of the worm groove to the rotary bunch builder device when, upon depression of the builder arm, the worm is moved into bunch building position, and in accordance with the present invention means are provided to prevent such. variation of engagement between the worm and therotarybunch building device.

. A simple form of means to this and con- .sists of a pin 51 which, should the worm be rotated by the rotary bunch builder device during main service wind, would engage the.

peripheral portion of the bunch builder device and arrest or stop further movement, and since the pin or stop 51 is located to come into action on the completion of a bunch, it insures that at the connncncement of the next bunch wound, the worm 41. will have the same peripheral portion" of its groove presented to the rotary bunch builder device and that the bunches on the new set of bobbins .Will' be commenced at the same point of the wormwhere the prcviously wound bunches had commenced.

The invention, therefore, provides a simple construction of bunch building attachmentwhich may be-associated'witb the usual builder mechanisms now in use to effect. first, the winding of uniform bunches of successive series of bobbins or filling carriers which shall be of the same size and amount of filling, and second, obviate the undesirable jump by passing from bunch building to regular service Wind-at the com pletion of the bunch. It also insures that bunches successively wound on a series of filling carriers or bobbins shall commence at the same point of .the worm at which other bunches or preliminary windings have. commenoed.

*In'the illustrated form of the invention,"

the rotary bunch builder device is in the form of a disa'whichis found to'be a good, practical feature, and consequently little or no traverse'is given to the yarn during the bunch: building operation, but, if desired, the rotary bunch builder device ma booth- ,erwise formed, with a somewhat rregular f l building member mounted on. the builder surface to give anydesired traverse to the yarn during the bunch building operation.

In any event, however, it"is desirable that not pass below or towards the head of the bobbin beyond about the central portion of the bunch, as otherwise the yarn may be 10 I the bunchwindings. The filling carrier. or

broken as the unwindings thereof approach bobbin, as illustrated'in Fig. 5, has the vbunch-53 Wound thereon in accordance with i the presentdisclosure of the invention, and
